What is a pump inverter?

Put simply, it is an inverter that is controlling a pump’s motor. There are several reasons why you might want to use an inverter on your pump: To save energy/costs. To prevent costly maintenance and down time.


How does a pump inverter work?

Inverter drives or variable speed drives allow the user to control the speed of the motor or pump to meet the exact demands of the system or process that it carries out. Variable speed drives, (also known as inverter drives or inverter drive systems), control how a pump is used.

AC solar pump price starts from PKR 15000  for 1 HP to 95000 for 10 HP depending on head or depth of water level. Above prices are including solar pump, controller, panel, structure, AC-DC wires, earthing, connectors and complete accessories.


As the name implies, inverter-duty refers to a gearmotor whose speed is controlled by an inverter, or VFD (variable frequency drive). The difference between an inverter-duty gearmotor and a standard gearmotor is in the construction. … In short, any application requiring adjustable speed, hence the use of a VFD.


It depends on the wattage of the water pump. But in general, you need 130 watts solar panels for a 100-watt water pump. If a panel produces 100 watts and you have a water pump of 300 watts, then you need 3 solar panels to run the pump.


While DC pump is more efficient than AC pump and required less solar panels to operate, it is difficult to maintain in remote areas as it needs specialized service centers, and you will not be able to run for emergency in night time, also its price is higher than AC pump.

If you are seeking for photovoltaic VFD inverters for solar powered water pumping system, then you are already arrived to the right store. Our SI20 series solar powered pump inverter is definitely the appropriate choice for you.

Veichi SI20, released to the global market at the end of 2015, is the updated version of SI10 PV pumping inverter. Comparing with SI10, the SI20 series are of enhanced working performance such as in stability, efficiency and other functions. Since the announcement, SI20 has gained more than 1000 successful application examples in various fields like agricultural irrigation, desertification control, stock farming, solar energy powered fountains and so forth. Below are the main features of SI20:
photovoltaic pump system

1. Convert DC to AC power

SI20 can convert the direct current generated by solar panels into alternating current to drive photovoltaic pumps.

2. Adjustable output frequency

It is capable of adjusting the output frequency automatically in line with the irradiation intensity.

3. Maximum Power Point Tracking function

Built-in with the MPPT (maximum power point tracking) function, so the photovoltaic pumping system can produce better power outputs to improve the working efficiency of pumps.
MPPT function

4. Store water, instead of storing power

The energy storing devices such as battery have been eliminated from the system, so all the AC power can be directly used to drive pumps with the lowest energy loss.
5. Asynchronous and synchronous motors are available
While our SI10 can only work with asynchronous 3 phase induction motors, the SI20 series can work perfectly with both asynchronous and synchronous 3 phase induction motors.
6. Support various kinds of pumps
Both the surface mount and submersible pumps are compatible with the photovoltaic pumping system.
7. Remote monitor function
SI20 has inbuilt S200-GPRS that users can monitor the whole photovoltaic pumping system online at home or other place via our PC remote monitoring system. On the basis of user-defined curve, SI20 can automatically calculate the present flow speed, flow per day, present power, total generation and more status parameters of the solar pumping system.
remote monitoring
8. USB data recorder
As SI20 has developed with the USB data recorder, so users can duplicate the data excel to monitor the PV pumping system offline at any time.
9. Complete protections
SI20 has designed with a wide range of protection functions such as water fulfill, dry run, low frequency, high voltage, short circuit, over heat, phase missing and more.
10. User-friendly
SI20 is designed with an intuitive operation panel along with detailed instructions, so it is convenient in installation, operation and maintenance. Additionally, the cooling and shielding effect is great.
Besides, Veichi Electric also provides other solar energy products such as PV inverter at wholesale price.
